IMPROVEMENT INISPRING AIR-PlsToLs.

Specification forming part ofLetters Patent No.: 178,233, dated June 6,1876; application led V' i February 16, 1876.

` Toa'll whom` 'it may concern:

Beit known 'that I, AUGUSTUS C. CAREY,

, of Malden, Middlesex county, Massachusetts, have invented certainImprovements in Air` d v Pistols, of which' the` following is aspecifica,`

tion: d n The drawings accompanyingthis specification represent, inFigure 1, a vertical and longitudinal section ot'an air-,pistol embody'-ing my improvements, whilelfig. 2'is a perspective view, and Fig.`3 aplan, of the adjacent ends of the barrel and air-magazine, the

former showing the barrel as'turned to one vside or exposed to receive aprojectile.` Fig.

4, in said drawings, is a perspective view ot' the adjacent ends of thebarreland air-charnber, showing a modification of my improvements. Fig".5 is a viewotl astirrnp-rod to be explained. Y i

` 1 In these drawings, A represents the frame or Stock of the pistol,consisting of a straight cylinder whose interior, B, constitutes theair.

magazine or chamber. Within this air-chamber Bis disposed aspringimpelled plunger, C, to which is" attached a rod, D, that passesrearward through the cap E, which closes the rear end of said chamber,the rod D serving to cock or set the plunger against the stressultaneously with this, and contain nothing, per se, which I now claim.`i

4 My present improvement `relates tothe peculiar method of attaching thebarrel to the st ock to convert the pistol into a breech-loading one;and'consists in pivoting such barrel at its rear end to the front end ofthe air-magazine to one side'of the ,common axes of the two, in suchmanner that by turning or partially rotating the barrel upon its pivotits bore is exposed and the projectile readily inserted. c .l

`My present improvements further embrace the employment, in connectionwith the plunger, of a rod or strap' bearing at bottom a vstirrup inlwhich to place the users foot, and

Y provided atthe other end with a hook orI other means of seizing holdof the rearfend of the` plunger-rod, in order that ample power may" beobtained to overcome thestressof the plunger-spring in cooking such4plunger. n

The drawings accompanying this specification represent' thel barrel at Gas secured at its rear 4end to an annular disk or hub, H,

which is pvoted at` its lower'part` to the front end of theair-magazineB, and eccentrically with respect to the bore ofthe latter and of thebarrel. i y f When thebarrel is in a closed or -firing position its borea is in alignment with, and constitutes, with a reduced diameter, acontinua,- `tion ofthe bore of the air-chamber, and the contiguous facesofthe hub vH and air-niagazine B are disposed obliquely to the axes ofthe two, in order that when the barrel is returned from an open to aclosed position the partsshall'crowd against each other and effeet anair-tight joint. y

A modification of this adaptation of the barrel would be,.as shown inFig. 4 of thedrawings, to add to the front of the air niagazine orcylinder A al lower branch or support, b, whose outer end is tubular, asshown at c, to receive and support in part the barrel G, which slidesWithin it, the depression or space f intervening between the tubularsupport b and air-magazine permitting ofthe introduction of theVprojectile `in the barrelwhen the latter is pulled forward.

The rear end of thebarrel is let'into a cor`` responding' countersink inthel air-magazine to obtain a close joint, and I prefer toY add to 4 thetop of the barrel a pointed stop or guide, g, d which` enters lacorresponding' notch, 'd, in the cylinder A, and determines the properposi-l One of the screws e which tion of the. barrel. confine the guideg to the barrel serves to determine the distance to which such barrelshall be pulled forward in the act of loading.

In this modicat-ion the barrel is pulled outward until the screw or stope abuts against v the` tubular support, which opens or exposes l therear end of such barrel. The projectile and the latter returned toplace.

H', in the accompanying drawings, repreis now inserted in this open endof the barrel,

sents'a rod orstrap, or equivalent 'objeet,pro vided at one end lWithetA hook, g', to enter a-n` eye, h, inthe rear end of theplunger-rod D,or otherwise adapted to seize, holdfof such rod, and at its other endprovided with :t stirrnp o'r handle, ,in which the users foot may beplaced to obtainA great power 4over the. t stress of the plunger-spring,and relieve the hand of the user of the labor of contracting such springin cooking 0 1' setting the plunger.

I clairne l. In .austin-spring pistol, the air-chamber or` cylinder, inconbinationfwith the bari-ei eoeentrieallyipivoted to the frontof-the'cylinder, and, when inrng position, communioating at itsrearfwith 'an air-passage leading from theeylinder, as shown Landsetforth.
